1.5A Low Quiescent Current 1.6MHz High Efficiency
Synchronous Buck Regulator
ISL8009A
The ISL8009A is a high efficiency, monolithic, synchronous
step-down DC/DC regulator that can deliver up to 1.5A
continuous output current. It is optimized for generating low
output voltages down to 0.8V. The supply voltage range of 2.7V to
5.5V allows for the use of single Li+cell, three NiMH cells or a
regulated 5V input. The ISL8009A uses current mode control
architecture to deliver very low duty cycle operation at high
frequency with fast transient response and excellent loop
stability. It has flexible operation mode selection of forced PWM
mode and automatic PFM/PWM with as low as 17μA quiescent
current, achieving high power conversion efficiency under light
load condition, hence maximizing battery life. High 1.6MHz
pulse-width modulation (PWM) switching frequency allows the
use of small external components.
The ISL8009A integrates a pair of low ON-resistance P-Channel
and N-Channel internal MOSFETs to maximize efficiency and
minimize external component count. The 100% duty-cycle
operation allows less than 400mV dropout voltage at 1.5A
output current.
The ISL8009A offers a 2ms Power-On-Reset (POR) timer at
power-up. The timer output can be reset by RSI. When shutdown,
ISL8009A discharges the output capacitor through a 100 Ω
resistor. Other features include internal digital soft-start, enable
for power sequence, overcurrent protection, and thermal
shutdown.
The ISL8009A is offered in a 2mmx3mm 8 Ld DFN package with
1mm maximum height. The complete converter occupies less
than 1cm 2 area.
